Transfer device and process for making up keratin materials

ABSTRACT

Process for making up an area of human keratin materials using a makeup device including a substrate having at least one transfer surface, and a coat of cosmetic colouring ink borne by the transfer surface and obtained by printing, using at least one digital printer, and a cosmetic coating comprising an oil borne by the transfer surface. The cosmetic coating is at least partially superposed on the coat of ink and laying above and/or below the coat of ink, and the process includes the step of simultaneously transferring onto the area to be made up all or part of the coat of ink and all or part of the coating superposed thereon.

TECHNICAL FIELD

The present invention relates to makeup application by transfer.

BACKGROUND

There is a need to cover keratin materials, especially the skin and thelips, with precise coatings, such as patterns, on the millimetre scale.

However, no practical and efficient method exists. Drawing a patterntakes a long time to do and requires the intervention of a professionalmakeup artist. Methods using a patch or a decal transfer aredisappointing, since the number of patterns is limited and it isdifficult to avoid folds in the support bearing the pattern. Thistechnique is, in particular, unsuitable for the face. On account of themovements of the facial skin, the support becomes cracked, thus giving adegraded and unaesthetic visual result.

There is a need for makeup patterns intended to cover a small area orindeed the entire area of the face or the lips.

There is a need to propose to each user a wide variety of patterns,colours, shapes and distributions, or even to propose to the user todefine his patterns, so as best to satisfy his particular request,without the need to have a large number of references at hand.

Moreover, if the area to be made up has imperfections such as marks,microreliefs, wrinkles or fine lines, the makeup pattern has a lessaesthetic result, not giving it a sharp, clean appearance.

There is a need for a makeup that is suited to the particularcharacteristics of the area of keratin materials to be treated. Thus,the makeup must occasionally be produced using a very thin coat ofcosmetic ink to be comfortable for the user to wear, for example in thecase of lip makeup.

There is a need to prepare the area to be made up so that the transferkeeps its precision completely intact and to have a beautiful, sharp andprecise appearance.

The present invention is directed toward meeting all or some of theseneeds.

SUMMARY

According to a first of its aspects, the present invention relates to aprocess for making up an area of human keratin materials using a makeupdevice comprising:

-   -   a substrate having at least one transfer surface, and    -   a coat of cosmetic colouring ink borne by the transfer surface        and obtained by printing, using at least one digital printer,        and    -   a cosmetic coating comprising an oil, the cosmetic coating being        borne by the transfer surface, the cosmetic coating being at        least partially superposed on the coat of ink and laying above        and/or below the coat of ink, the process comprising the step of        simultaneously transferring onto the area to be made up all or        part of the coat of ink and all or part of the coating        superposed thereon.

The term “human keratin materials” denotes the skin, including thescalp, the lips, the nails, the hair, the eyelashes and the eyebrows;preferably the skin.

The term “digital printer” means a machine for printing in the form ofpixels using digital data, different from a machine comprising aprinting form. The use of at least one coat of cosmetic ink obtained byprinting using a digital printer advantageously makes it possible toobtain great precision for a complex and customizable makeup.

The colouring ink and the coating deposited are intended to be placed incontact simultaneously with the keratin materials so as to obtain, bytransfer, a makeup result on the keratin materials.

The process of the invention is easy to perform and allows transfer in asingle gesture with good relative positioning of the pattern and thecoating, avoiding pattern shifts.

The makeup effect obtained is very interesting. The keratin materials,especially the skin, are coated with a coating and it is also possibleto see at least one pattern that is precise.

The invention allows makeup application that combines a standardcolouring cosmetic composition with a customizable pattern. Theinvention also makes it possible to integrate the composition,especially a foundation, and the pattern, which allows a certain levelof discretion, if so desired. Good precision of the pattern ismaintained, by means of printing, without it being impaired by thecoating composition.

The invention also makes it possible to make up areas of the skin bysmoothing these areas to improve their visual aspect.

The presence of the coating also improves the visual rendering of thepatterns, over the entire made-up area, without allowing the skindefects to show through.

According to another aspect, the invention also relates to a process formanufacturing a transfer device for making up human keratin materials,comprising a substrate having at least one transfer surface, thisprocess comprising the following steps:

-   -   printing at least one coat of at least one cosmetic colouring        ink on the transfer surface using at least one digital printer,    -   applying at least one cosmetic composition to the transfer        surface to form a coating, the cosmetic coating being at least        partially superposed on the coat of ink, the coat of colouring        ink and the cosmetic coating being intended to be transferred        simultaneously onto the keratin materials so as to obtain a        makeup result on the keratin materials.

The printing of the coat of ink may be performed on the transfer surfacealready partly covered with the coating.

The coating may at least partly be produced after printing the coat ofink onto the transfer surface.

In one embodiment example, the colouring ink is printed in a predefinedpattern, the process comprising a step of choosing and/or making thepattern by a user and of transmitting, by means of a machine connectedto at least one printer that performs the printing, information relatingto this pattern.

The machine may be a computer, an advanced portable telephone, alsoknown as a “smartphone”, or a tablet computer. The machine may beconnected physically and/or by means of a data exchange network to thesaid printer.

The printer may be an inkjet printer, for example a thermal orpiezoelectric printer, a sublimation printer or a laser printer.

In one example, the printer is a laser printer arranged to allow theformation by electrophotography or magnetophotography of a coat of inkhaving a pattern on a transfer surface using at least one cosmetic tonerand to deliver the toner present on the transfer surface in a state thatis sufficiently free to allow it to be taken up or transferred bycontact with the human keratin materials.

The term “cosmetic toner” should be understood as meaning a pulverulentcosmetic composition that is compatible with the formation of an imagevia an electrophotographic or magnetophotographic process as used inlaser printers. Preferably, it is a toner that is suitable forelectrophotographic use.

The toner is cosmetic in the sense that it is compatible with anapplication to human keratin materials. Depending on the surface to bemade up, the formulation of the toner may be different. For example, foran application to the hair or the nails, it is possible to use certaincompounds that might not be used for an application to the lips, forexample. The printer may be a food-grade inkjet printer such as theGatocopy A426 machine allowing printing onto non-flat objects.

In one embodiment example, the printing is performed directly onto anon-flat transfer surface, corresponding especially to the outer surfaceof a roller.

The printing may use several different inks, especially inks ofdifferent colours. The printing may use at least three, especially atleast four, five, six, seven, eight, nine, ten, eleven or twelvecolouring inks of different colours.

The printing may use only colouring inks that produce primary colours.As a variant, the printing may use both colouring inks that produceprimary colours and at least one colouring ink that produces anon-primary colour.

The printing of the colouring ink may be three-colour or four-colourprinting.

The pattern obtained by printing may comprise several areas of differentcolours. As a variant, the pattern obtained by printing is a flat tint.

The colouring ink may be deposited in several printing passes. In otherwords, a first fraction of the colouring ink may first be printed ontothe transfer surface, followed by a second fraction of the colouring inkon all or part of the first fraction.

The printing of the coat of ink may be performed on the transfer surfacealready covered with the coating.

The printing may be performed on a dry or non-dry coating. One variantconsists in depositing a coating of a composition onto a transfersurface, waiting for it to dry and then printing.

In one variant, the coating is produced after printing the coat of inkonto the transfer surface.

The transfer step by placing the transfer surface in contact with thearea to be made up is performed, for example, by exerting a pressure onthe surface of the substrate opposite the transfer surface.

A process according to the invention may also comprise a step consistingin moving the transfer surface away from the area of the human keratinmaterials after the coat of ink and the coating have been transferred.

In one embodiment example, the coat of colouring ink is printed onto thetransfer surface and then at least partly covered with a coating.

In one variant, the transfer surface is at least partly coated with afirst coating, the coating comprising, for example, a pigment and/or adye.

The coat of ink is then printed onto the first coating.

A composition may then be applied to form a second cosmetic coating.

Advantageously, the colouring ink is not entirely dry on the substratewhen it is applied to the keratin materials. The colouring ink may be influid form when it is applied to the keratin materials.

All or part of the colouring ink borne by the transfer surface may beapplied by transfer to the keratin materials.

In one embodiment example, at least 25%, especially 50%, especially 75%and especially substantially all of the colouring ink initially presenton the transfer surface is applied by transfer to the keratin materials,preferably without addition of an intermediary fluid compound.

In one embodiment example, the application of the colouring ink isperformed by application with pressure of the transfer surface onto thekeratin materials.

The simultaneous transfer of the colouring ink and of the coatingcomposition onto the area to be treated may be performed withoutrubbing.

Advantageously, the area of keratin materials intended to receive thecolouring ink has not been pretreated at the time of the simultaneoustransfer of the colouring ink and of the coating composition.

According to another aspect, the present invention relates to a transferdevice for making up human keratin materials, comprising:

-   -   a substrate having at least one transfer surface,    -   a coat of cosmetic colouring ink borne by the transfer surface        and obtained by printing, using at least one digital printer,        and    -   a cosmetic coating comprising an oil borne by the transfer        surface,        the cosmetic coating laying above or below the coat of ink, at        least partially superposed on the coat of ink,        the colouring ink and the cosmetic coating being intended to be        applied to the keratin materials, especially by being placed in        contact with the keratin materials, so as to obtain, by        transfer, a makeup result on the keratin materials.

Substrate and Transfer Surface

In one embodiment example, the substrate of the makeup device accordingto the invention comprises at least one translucent or transparent area.

The translucent or transparent area allows a user to see through thesubstrate and thus to visualize more easily the surface to be made upbefore transferring the colouring ink. The presence of a translucent ortransparent area thus advantageously contributes towards facilitatingthe production of a precise makeup result on the keratin materials.

The translucent or transparent area of the substrate can be totally orpartly superposed with the coat of colouring ink, and especially mayoverlap it.

The coat of colouring ink may be superposed in its entirety on thetranslucent or transparent area of the substrate. As a variant, onlypart of the coat of colouring ink is superposed on the transparent areaof the substrate.

The substrate may be made of a transparent or translucent material. Inthis case, the translucent or transparent area extends over the entiresurface of the substrate.

As a variant, the substrate is opaque over all or part of its surface.

The substrate may be a flexible sheet or a rigid plate. It may be madeof plastic (for example polyethylene or polystyrene). It may be woven ornonwoven. It may be made of organic or mineral material. It may be analuminium foil.

The transfer surface of the substrate may be defined by all or part of:the outer surface of an applicator roller, the surface of an applicatorpad, an element in sheet form, a patch, the surface of a porous foam,especially a sponge, a wipe, a coarse brush, a fine brush or a flockedtip.

The transfer surface is defined, for example, by all or part of thesurface of a deformable sheet mounted on the surface of an applicatorroller.

The transfer surface may retain the colouring ink by capillary action.

The transfer surface may be planar or nonplanar.

The transfer surface may be elastically deformable. Thus, in a firstconfiguration, the transfer surface may be flat, and, in a secondconfiguration, the transfer surface may be incurved, for example so asto take the shape of the keratin materials to be made up.

In one embodiment example, the transfer surface is detachable from apart of the substrate.

As will be detailed below, the substrate may be configured so that thetransfer surface takes a first form, for example substantially flat,during printing, and a second form, different from the first, during theapplication of the colouring ink to the keratin materials.

The second form advantageously corresponds to the form of the surface ofthe keratin materials intended to be coated with the colouring ink, forexample the form of a part of the face.

In one embodiment example, the substrate comprises an indicationregarding the nature of the keratin materials intended to be made upwith the colouring ink. This indication may be printed with the same inkor otherwise as that intended to be transferred.

The substrate is preferentially based on a non-absorbent material, forexample a plastic film. The substrate is advantageously non-porous, atleast on the face intended to receive the print.

In one embodiment example, when the colouring ink is intended to beapplied to the cheeks and/or the nails, the substrate may have athickness of greater than or equal to 1 mm, especially 3 mm, for exampleranging from 1 to 5 mm.

In one embodiment example, when the colouring ink is intended to beapplied to the area around the eyes and/or to the lips, the substratemay have a thickness of greater than or equal to 3 mm, especially 1 cm,for example ranging from 3 mm to 20 mm.

In one embodiment example, when the colouring ink is intended to beapplied to the nose and/or in the area of the ears, the substrate mayhave a thickness of greater than or equal to 1 cm, especially 3 cm, forexample ranging from 1 to 4 cm.

Thus, the substrate advantageously has a thickness adapted to the areaof keratin materials to be made up.

The thickness of the substrate corresponds to its maximum dimensionmeasured perpendicular to the transfer surface.

The substrate may be reusable. For example, printing is performed on thesubstrate, which is accessible for the transfer, but does not leave theprinter. Thus, after use, the printer can reintegrate the substrate,clean it and make it ready for a new print.

Colouring Ink

The ink borne by the transfer surface preferably comprises a dyestuff.

Dyestuff

The dyestuff may comprise one or more dyes as described below.

The dyestuff may be present in the ink in a mass content ranging from0.01% to 60%, preferably ranging from 0.1% to 40%, or even from 0.1% to30% and preferentially ranging from 0.5% to 20%, relative to the totalmass of the ink.

The colouring ink may comprise one or more dyestuffs chosen fromwater-soluble dyes, liposoluble dyes, pulverulent dyestuffs such aspigments, especially nacres, and glitter flakes, or alternativelycolouring polymers.

The term “pigments” should be understood as meaning white or coloured,mineral or organic particles of any form, which are insoluble in thecosmetic medium, and which are intended to colour the cosmetic ink.

The term “nacres” should be understood as meaning iridescent particlesof any form, in particular produced by certain molluscs in their shell,or else synthesized.

The pigments may be white, black or coloured, and mineral and/ororganic. Among the mineral pigments that may be mentioned are titaniumdioxide, optionally surface-treated, zirconium oxide or cerium oxide,and also zinc oxide, iron (black, yellow or red) oxide or chromiumoxide, manganese violet, ultramarine blue, chromium hydrate and ferricblue, and metal powders, for instance aluminium powder and copperpowder.

The dyeingpolymers are generally copolymers based on at least two differentmonomers, at least one of which is a monomeric organic dye. Suchpolymeric dyes are known to those skilled in the art. Reference may bemade, for example, to the following documents: U.S. Pat. Nos. 5,032,670;4,999,418; 5,106,942; 5,030,708; 5,102,980; 5,043,376; 5,104,913;5,281,659; 5,194,463; 4,804,719; WO 92/07913 or EP 1 048 282.

The printing may use several different inks, especially inks ofdifferent colours.

The printing may use at least three, especially at least four, five,six, seven, eight, nine, ten, eleven or twelve cosmetic inks ofdifferent colours.

The pattern formed by the colouring ink borne by the transfer surfacemay be coloured when observed under white light in the visible region(400 nm-800 nm). As a variant, the pattern is colourless under whitelight in the visible region, but may appear coloured when submitted to achemical and/or energy stimulus, such as exposure to UV (365 nm-400 nm),for example when the colouring ink contains a photochromic orfluorescent dyestuff and/or dihydroxyacetone (DHA).

The printing may use only colouring inks that produce primary colours.As a variant, the printing may use both colouring inks that produceprimary colours and at least one ink that produces a non-primary colour.

In one variant, the printing may use colouring inks that produce blackand/or white.

The printing of the ink may be three-colour or four-colour printing.

The pattern obtained by printing may comprise several areas of differentcolours.

As a variant, the pattern obtained by printing is a flat tint.

The pattern formed by the cosmetic ink printed on the transfer surfacemay be of any type.

Advantageously, the pattern may reproduce the appearance of reliefand/or colour heterogeneities of the skin, for example freckles or amole.

The coat of colouring ink may comprise several inks.

The colouring inks deposited by printing may be deposited onto thetransfer surface in the form of dots and/or of raster lines, so as toform a half-tone image, for example a monochromatic or polychromaticimage.

The coat of colouring ink may comprise several colouring inks ofdifferent colours, each deposited in dots.

Advantageously, the colouring ink is not entirely dry on the substratewhen it is applied to the keratin materials. The colouring ink may be influid form when it is applied to the keratin materials.

All or part of the colouring ink borne by the transfer surface may beapplied by transfer to the keratin materials.

In one embodiment example, at least 25% by mass, especially 50%,especially 75% and especially substantially all of the coat of colouringink initially present on the transfer surface is applied by transfer tothe keratin materials.

In one embodiment example, the application of the colouring ink isperformed by application with pressure of the transfer surface onto thekeratin materials.

The dyestuff may comprise one or more dyes, in particular acid dyesand/or colouring polymers, and/or one or more pigments, the pigmentspossibly being charged with dyes.

In one embodiment example, the dyestuff comprises one or more colouringagents that may be revealed under the action of an energy and/orchemical stimulus, for example photochromic compounds and/ordihydroxyacetone (DHA).

Preferably, the colouring ink present on the device is not entirely dry.

The application of a colouring ink that is not entirely dry onto thekeratin materials facilitates the transfer of the ink.

The colouring ink may be in fluid form when borne by the transfersurface and before application to the keratin materials.

Advantageously, the fluid colouring ink has a viscosity ranging from 1to 30 mPa·s, at 25° C.

The viscosity of an ink of the invention may be measured according toany process known to those skilled in the art, and especially accordingto the following conventional process. At 25° C. using a Rheomat 180viscometer, equipped with a spindle rotating at 200 rpm, a personskilled in the art can select the spindle for measuring the viscosityfrom the spindles M1, M2, M3 and M4 on the basis of his generalknowledge, so as to be able to perform the measurement.

When the ink is in the form of a cosmetic toner, this toner maycomprise, besides a colouring agent, a compound for controlling theelectrical charge, a particular additional filler, a lubricant, a waxand/or a binder.

Preferably, the particles of the toner have a mean size of between 1 and16 μm. The toner comprises, for example, pigments with a particle sizeof between 1 and 10 μm.

Measurement of the Ability of the Colouring Ink to Transfer without theNeed to Add an Intermediary Fluid Compound

As mentioned above, the colouring ink is, particularly preferably,capable of transferring onto the keratin materials without the additionof an intermediary fluid compound.

To check whether a given colouring ink has this property, the coat ofcolouring ink under consideration borne by a surface is placed incontact with a sample of artificial skin sold by the company Beaulaxunder the brand name Bioskin ref #white 061031-2.

The contact is performed for a time of 1 s by applying a pressure of5000 pascals (i.e. 50 g/cm²) under atmospheric temperature and pressureconditions (20° C. and 1 bar). No intermediary fluid compound is addedeither to the colouring ink or to the sample before or during thecontact.

A visual evaluation is performed.

If the colouring ink transfers onto the keratin materials, then thecolouring ink is considered as being capable of transferring onto thekeratin materials without the addition of an intermediary fluidcompound.

In one variant, the devicecomprises a first and a second cosmetic coating, borne by the transfersurface and located on either side of the coat of cosmetic ink. Thefirst and the second cosmetic coatings in particular comprise differentcompositions.

The first and/or the second cosmetic coating may be coloured. Thecoating is, for example, coloured a colour that is difficult to print,for example white or black, or a colour close to the flesh tone of theskin to be made up, such as a flesh colour.

As a variant, the coating is not itself coloured.

The first and/or the second cosmetic coating is obtained, for example,from a composition chosen from a foundation, a lip gloss, a lip balm, alipstick and an eyeshadow.

The coating may be a skincare product.

In one example, the colouring ink integrated into the coating is capableof transferring onto keratin materials without addition of anintermediary fluid compound, especially a liquid. In other words, thecolouring ink may transfer onto the keratin materials by simple contactof the area intended to be made up with the said colouring ink, withoutit being necessary to apply an intermediary liquid intended to improvethe transfer of the ink, as in the case of decal transfers.

The devices may differ by the form and/or the composition of thesubstrate, in particular the transfer surface intended to engage withthe keratin materials.

The devices may differ by the chemical nature of the colouring ink theybear and/or by the pattern thereby formed.

The assembly may comprise one or more ink cartridges and substratedeformation means.

The assembly may also comprise a suitable printer.

When an intermediary compound that is useful for fluidizing the transfercompound(s) is used, the intermediary compound may be added within thecolouring ink to the transfer compound(s) after printing.

The intermediary compound may be added, within the colouring ink, to thetransfer compound(s) by any known means, especially by spraying.

The intermediary compound is preferably added to the transfercompound(s) before the application of the colouring ink to the keratinmaterials, while the colouring ink is still borne by the transfersurface.

In one embodiment example, the colouring ink is brought to a temperatureof between 30° C. and 60° C. before being applied to the keratinmaterials. As a variant, the colouring ink is brought to a temperatureof between 30° C. and 60° C. while it is in contact with the area of thekeratin materials intended to be coated with the colouring ink.

When the colouring ink is intended to be brought to a temperature ofbetween 30° C. and 60° C. prior to its application, the colouring inkbrought to this temperature may be applied to the nails so as to producea makeup result thereon by transfer.

When the transfer surface is detachable from a part of the substrate,the user can first detach the transfer surface from the rest of thesubstrate and then apply by transfer onto the keratin materials thecolouring ink present on the transfer surface thus detached.

The colouring ink may be brought to a temperature of between 30° C. and60° C. by being placed close to a heating member. As a variant, thecolouring ink obtained just after printing may already be at such atemperature; the user can then apply to the keratin materials thecolouring ink at this temperature, before it cools.

According to yet another aspect, the present invention relates to a kitfor manufacturing a device according to the invention as describedpreviously.

The kit may comprise, in the same packaging:

-   -   a) a printer cartridge containing at least one cosmetic        colouring ink,        -   a cosmetic composition comprising an oil that is capable of            transferring onto the keratin materials, the composition            being contained in a packaging assembly,    -   b) a substrate having at least one transfer surface intended to        receive a coating of the composition and a coat of colouring ink        printed using a digital printer.

The composition packaging assembly is, in a known manner, any packagingthat is suitable for storing cosmetic compositions (especially a bottle,tube, spray bottle or aerosol bottle).

DETAILED DESCRIPTION

FIGS. 1 to 3 show a makeup device 1 according to the invention,comprising a substrate 2 made of a flexible and deformable material, thefront face of which constitutes a transfer surface 3 intended to receivea coat of cosmetic colouring ink 4, to produce a makeup result bytransfer.

To deposit the coat of colouring ink 4 onto the transfer surface 3, useis made of a digital printer, which deposits the ink dots incorrespondence with the pixels of an image to be reproduced.

A pattern 40 representing in negative the image to be reproduced isprinted directly onto the transfer surface 3. FIG. 1 shows the device 1after printing, once removed from the printer, the transfer surface 3bearing a coat of cosmetic ink 4.

All or part of the area of the transfer surface 3 superposed on the coat4 is preferably smooth and has a roughness of less than or equal to 1mm, especially between 1 and 100 μm and preferably less than or equal to50 μm. The roughness is measured using a roughness meter, the tip ofwhich has a radius of curvature of 10 mm, and the force of which,applied to the material to be characterized, is 6 mN.

The coat of colouring ink 4 may form any type of pattern, for example inthe form of a heart and of text as illustrated. The pattern may consistof several inks.

The substrate 2 may bear an indication 7, for example formed byprinting, for providing information regarding a recommended positioningfor the makeup, or providing information regarding the nature of thekeratin materials intended to be made up with the ink 4, or the like.

A coating 6 is then applied as illustrated in FIGS. 2 and 3. The coatingis, for example, coloured and corresponds to the application of afoundation.

The invention is not limited to a type of coating. The coating may be ofany type known for the cosmetic treatment of, in particular for makingup, the body or the lips.

In this example, the cosmetic coating 6 covers the coat of ink 4, beingtotally superposed on the pattern of the coat of ink 4. As shown by thesection III-III of FIG. 3, the coating 6 integrates the ink of the coat4 while at the same time preserving the pattern 40. To help thisincorporation of the coat of ink 4 into the coating 6, the user canoptionally make rectifications in order, for example, to attenuate theedges.

Preferably, the substrate 2 has at least one non-opaque area 5, which ispreferably transparent or translucent, and which may totally or partlybe superposed with the coat of colouring ink 4 and the coating 6. Thetransparent area 5 allows the user to see through the substrate 2 andthus to visualize the surface to be made up through the device 1 whenthis device is superposed on the said surface.

All of 4 and of the coating 6 may, as illustrated, be superposed on thetransparent area 5. In one variant, not shown, only part of the coatingand/or of the coat of colouring ink is superposed on the transparentarea 5.

The substrate 2 may be made of a transparent material. The transparentarea 5 then extends over the entire surface of the substrate 2.

The substrate 2 may bear an indication 7, for example a print, forproviding information regarding a recommended positioning for themakeup, for example a reproduction, the right way around and at reducedscale, of the pattern to be transferred, as illustrated, or the natureof the keratin materials intended to be made up with the colouring ink4, or the like, and may also provide information regarding the colourand/or pattern reference.

The substrate 2 is preferably made of a flexible material. As a variant,the substrate 2 is made of a rigid or semi-rigid material.

The device 1 is then brought close to the area of skin P to be made up,which is preferably dry, so as to place the coat of colouring ink 4 andthe coating 6 simultaneously in contact with the area of skin P to bemade up, and the user then applies a pressure allowing the colouring ink4 and the coating 6 to be transferred onto the area to be made up P.During the contact with the keratin materials, the substrate 2 ispreferably not moved sideways so as not to affect the appearance of thetransferred pattern.

The substrate 2 bearing the transfer surface 3 is removed. The makeupresult obtained combines the pattern corresponding to the ink and thecoating. Good precision of the pattern is maintained, by means ofprinting, without it being impaired by the coating.

In one variant, not shown, a coat of ink forming coloured patterns isprinted on a transfer surface, coating is applied to a transfer surfaceusing a lip gloss, a lip balm or a lipstick. The transfer surface isthen placed on the area of the lips. A standard makeup result isobtained in a single gesture with the coating composition combined withthe patterns.

FIGS. 4 and 5 schematically show various steps of another embodiment ofa makeup process according to the invention.

FIG. 4 shows a transfer surface 3 of a substrate 2 onto which has beenapplied a coating 6, for example a foundation coat, to which isoptionally added an additional colour coat. It is possible to performone and then the other, or vice versa.

To deposit a coat of colouring ink 4 onto the transfer surface 3 coveredwith the coating 6, use is made of a digital printer, which deposits theink dots in correspondence with the pixels of an image to be reproduced.It is possible to modify at will one's patterns by referring to alibrary of patterns, or even by constructing one's own patterns (colour,shape, distribution).

The device 1 is then brought close to the area of skin P to be made up,which is for example dry, so as to place the coat of colouring ink 4 andthe coating 6 simultaneously in contact with the area of skin P to bemade up, and the user then applies a pressure allowing the colouring ink4 and the coating 6 to be transferred onto the area to be made up P.During the contact with the keratin materials, the substrate 2 ispreferably not moved sideways so as not to affect the appearance of thetransferred pattern.

The substrate 2 bearing the transfer surface 3 is removed. Skin defectsare masked by means of the foundation. The patterns produced by thetransferred coat of ink are also detected. Although positioned betweenthe area P of skin and the coating 6 of foundation, the patterns arevisible. Thus, a visual result that is pleasant since it is not toohomogeneous is obtained.

The makeup process is very practical to perform and the relativepositioning of the coating and of the coat of ink is done successfullysince it is performed in a single gesture.

EXAMPLES Example 1 (This Example Corresponds to FIGS. 6 and 7)

The substrate 2 is then placed on the arm so as to have contact betweenthe coating 6, the coat of ink 4 and the area P of skin to be made up.

When the sheet is removed, it is found that the foundation istransferred along with the small grains and that the small grains areentirely visible, despite the covering power of the foundation, as shownin FIG. 7.

Example 2

This example corresponds to FIGS. 1 to 3.

A coat of ink 4 is printed on the transfer surface 3 of a substrate 2similar to the plastic sheet of Example 1.

The transfer surface 2 is then covered with a coating 6 of foundation ofExample 1.

The whole is then applied to the skin, the coating 6 and the coat of ink4 being in contact with the area P to be treated.

The substrate is removed. The makeup result obtained combines thepattern and the foundation. The pattern is integrated into thefoundation, which affords a certain amount of discretion. Good precisionof the pattern is maintained, by means of printing, without it beingimpaired by the foundation.
